P&C is CI, just the pipe side of things. Your best bet is TobaccoReviews.com. I've not smoked any of those, but like cigars there are way more to try than can ever be smoked.

The Borkum Riff is an OTC pipe tobacco, and some people love it, just like some people love Captain Black. Personally I don't, but I do keep Prince Albert on hand. Just because it's an old school OTC blend does not in and of itself make it bad.

Unless its mixture 79. Just avoid that stuff and all should be good.
